Schneider Electric C10F1TM030 NSX100F 1P 30 A TM-D AC/DC Breaker

C10F1TM030: ComPacT NSX100F 1P breaker, TM-D 30 A

The C10F1TM030 is a Schneider Electric ComPacT NSX100F circuit breaker with one pole, a TM-D thermal-magnetic trip unit rated 30 A, designed for both AC and DC. The datasheet describes it as: ComPacT NSX100F AC/DC, 18 kA at 240 VAC, TMD trip unit 30 A, 1 pole 1d. Seven Star LLC supplies the C10F1TM030 in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference: the NSX100 frame carries up to 100 A, the F letter is the breaking-capacity level (18 kA at 240 V AC for this one-pole version), and the datasheet’s trip unit name is TM-D with a fixed 30 A thermal setting and a fixed magnetic setting of 300 A.

Technical specifications of the C10F1TM030

TM-D thermal-magnetic protection on the C10F1TM030

The TM-D unit is thermal-magnetic: a bimetal element for overload (L) and a magnetic element for short-circuit (I). Both are fixed on this reference. The long-time pick-up is fixed at 1 x In, which is 30 A, and the instantaneous pick-up is fixed at 300 A, about 10.0 times In (calculated).

Fixed settings keep the device simple and free from mis-adjustment, but they also mean the protection cannot be tuned for motor inrush or for selectivity. The datasheet lists no earth-leakage protection. If a load needs adjustable thresholds, a breaker with an adjustable or electronic trip unit is the route.

Voltage, breaking capacity and DC use of the C10F1TM030

The datasheet gives two sets of ratings. On AC, Ue is 277 V and Icu and Ics are 18 kA at 220/240 V; on DC, Ue is 250 V and Icu and Ics are 36 kA. A single-pole breaker has one contact gap, so it fits circuits where one conductor is switched: a phase-to-neutral circuit on a 400 V system, a single-phase supply, or a DC circuit up to 250 V where the polarity arrangement permits it.

For three-phase loads or for circuits that need all poles to open together, a multi-pole device is the correct choice; a multi-pole NSX100F version with its own datasheet ratings is the right basis.

Dimensions and dissipation of the C10F1TM030

The datasheet lists 4.03 W of dissipation per pole. With a width of only 35 mm and a weight of 0.7 kg, the C10F1TM030 allows high-density boards; the heat from adjacent poles should be included when the cubicle ventilation is calculated.

Mounting is on a backplate or flat on the back, with front connections at 35 mm pitch. The front face is Class II; IP40 and IK07 apply, so installation is inside an enclosed panel. The overvoltage category is IV for this single-pole version.

Related references to the C10F1TM030

The same single-pole NSX100F family is available at other ratings. The closest neighbour in the range we handle is C10F1TM020, which differs in the thermal setting and the fixed magnetic pick-up (20 A and 190 A), while the frame, voltage and breaking capacity are the same. Other ratings exist in the family; ask us for current availability.

Choose between neighbouring ratings on the load current and conductor size, not on the breaker alone: the breaker rating must protect the cable.

Installing and maintaining the C10F1TM030

Mount the C10F1TM030 on the backplate or flat on the back as the installation instructions allow, connect the cable to the front terminals and torque it to the manufacturer’s value. Switch the toggle through its positions to confirm free operation, and record the nominal 30 A setting on the circuit schedule.

Maintenance is limited: periodic inspection of terminals for heat discolouration, a manual operation test and, after any trip, a check of the cause before reclosing. Mechanical durability is 20000 cycles; electrical durability is 20000 cycles at 277 V In/2 and 10000 cycles at 277 V In.

Applications in Oman and the GCC

In Oman and the GCC, a 30 A one-pole breaker fits branch circuits for small motors, heaters, socket outlets on industrial sites and dc auxiliary supplies up to 250 V in substations. In hot rooms, the thermal element sees ambient heat, so ratings should be checked against the operating temperature.
