Schneider Electric GV2L04 TeSys GV2 0.63 A Motor Breaker

GV2L04: rotary handle, magnetic only motor circuit breaker

In the TeSys GV2 family the GV2L04 is the magnetic version at 0.63 A. Its datasheet lists a rotary handle, a magnetic tripping current of 9.3 A and no thermal adjustment range, which is the visible sign that overload protection has to come from somewhere else in the motor circuit.

Reading the reference against the datasheet: the device short name is GV2L, which the datasheet pairs with a rotary handle and magnetic trip technology; the digits after the family letters follow the current band, here 0.63 A.

The datasheet gives the range as TeSys Deca and the product name as TeSys GV2, with the application stated as motor protection. Rated operational voltage is 690 V AC 50/60 Hz, rated insulation voltage 690 V AC 50/60 Hz and the rated impulse withstand 6 kV.

GV2L04 technical specifications

GV2L04 compared with neighbouring TeSys GV2 ratings

The table lists the closest GV2 references by current. Moving one step up or down changes the thermal range, the magnetic trip and the motor power it is intended for, while the frame stays the same. Neighbouring references are GV2P02, GV2P03, GV2P04 and GV2ME04.

Control style is part of the reference letters within the GV2 frame: GV2ME is push-button thermal-magnetic, GV2P rotary thermal-magnetic and GV2L rotary magnetic-only. Check the exact current band when changing style. The 0.4–0.63 A band exists in three styles in this group, GV2L04 (magnetic only, 9.3 A trip), GV2ME04 (push-button) and GV2P04 (rotary).

Dimensions, terminals and mounting of the GV2L04

The GV2L04 is 45 mm wide, 89 mm high and 97 mm deep. It clips onto a 35 mm symmetrical DIN rail and can also be screwed to a plate (two M4 screws). Mounting is horizontal or vertical. Power terminals are screw clamp terminals, with two conductors per terminal: 1–6 mm² solid; 1.5–6 mm² flexible without cable end; 1–4 mm² flexible with cable end.

Environmental limits from the datasheet are -20 to 60 °C in operation and -40 to 80 °C in storage, an altitude limit of up to 2000 m, and protection IP20. Power dissipation is 1.8 W per pole, so the heat released inside the enclosure at full load is about 5.4 W for the three poles; add this to the enclosure thermal budget in a Gulf plant room.

Motor ratings listed for the GV2L04

The datasheet ties this breaker to specific motor sizes at each supply voltage. These figures are the rated motor powers for the AC-3 category and are what a motor schedule should be matched against, not only the current.

Rated duty is uninterrupted, and the durability figures are given in the table of specifications.

Selection checklist and RFQ details for the GV2L04

• Motor nameplate current and voltage, checked against the 0.63 A range and the motor kW table
• Required control style: rotary handle
• An overload relay is needed behind the breaker because this version has no thermal element
• Prospective short-circuit current at the board against the 100 kA rating at 400/415 V
• Terminals: screw clamp terminals; check the cable size and ferrule practice
• Space for a 45 mm wide device, 97 mm deep, and ambient heat inside the enclosure
• Accessories such as auxiliary contacts, trip indicators or busbar links if the design uses them

When requesting a quotation, include the following with the part number:

• Part number GV2L04 and quantity
• Motor power, voltage and full-load current
• Replacement or new build, and the existing breaker marking
• Delivery location and required date

Breaking capacity of the GV2L04 by voltage

Short-circuit breaking capacity falls as system voltage rises, which is the reason to read the whole table instead of a single headline value. The service breaking capacity Ics is shown as a percentage of Icu.

At 400/415 V AC the rating is 100 kA, which is the figure that matters on most Gulf 400 V distribution boards; compare it with the prospective fault level at the point of installation and with any upstream protection before relying on it.

Using the GV2L04 in Oman and the GCC

Motor starters are everywhere in Gulf plants, and this breaker suits small dosing pumps, instrument-air and ventilation fans, valve actuators, conveyors and other fractional-kW drives. The datasheet lists motor powers up to 0.37 kW across its voltages, which is what the GV2 frame is built for. Typical sites are desalination and water treatment, power auxiliaries, oil and gas utilities, petrochemical units and commercial HVAC.

Heat and dust drive the real life of a breaker. With an operating limit of -20 to 60 °C and protection of IP20, the device belongs inside a ventilated or air-conditioned enclosure rather than on an open wall in summer sun. For a retrofit, send the nameplate and the old breaker marking and we will match it.

How the GV2L04 protects the motor feeder

The only trip element in the GV2L04 is magnetic. At 9.3 A the breaker opens instantly, which for a 0.63 A rating is a fixed threshold of roughly 14.8 times the rated current. There is no thermal setting dial, so there is nothing to adjust on site, and the datasheet does not list phase-failure sensitivity for this version.

This makes the GV2L04 a good fit where the motor is already protected against overload by a relay, a soft starter or a drive. The breaker then provides isolation and short-circuit protection, while the thermal function stays with the equipment that knows the real motor load. Do not use it alone as motor overload protection.
