Schneider Electric RPM41F7 Harmony RPM 4 C/O 15 A Relay 120 V AC

RPM41F7 power plug-in relay, 4 CO, 15 A, 120 V AC coil

The RPM41F7 is a Schneider Electric product listed in the datasheet as: plug-in relay, Harmony electromechanical relays, 15A, 4CO, lockable test button, 120V AC. The RPM41F7 is a Harmony RPM power plug-in relay with four changeover contacts rated 15 A and a 120 V AC coil. It is a larger relay than the RXM and handles substantial loads on several poles. Seven Star LLC supplies the RPM41F7 in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference: RPM is the power relay series, 4 the four poles, 1 the version code, F7 the 120 V AC coil.

Technical specifications of the RPM41F7

Power contacts of the RPM41F7

Rated operational current: 15 A 277 V AC UL; 15 A 28 V DC UL; 15 A 250 V AC NO IEC; 15 A 28 V DC NO IEC; 7.5 A 250 V AC NC IEC; 7.5 A 28 V DC NC IEC. Coil or control voltage: 120 V AC 50/60 Hz. Contacts: 4 C/O. Mechanical durability: 10000000 cycles. Electrical durability: 100000 cycles resistive.

The RPM series combines a high current with several poles in a larger body. The lockable test button allows manual operation during commissioning.

Placement of the RPM41F7 among relays

The RPM is selected when the RXM contact rating is not enough yet a contactor is more than needed. It is a robust choice for switching motors of small size, heaters and lamp groups.

Selection checklist for the RPM41F7

• Four C/O at 15 A.
• Coil: 120 V AC.
• Socket for RPM.
• Test button.
• Load.
• Space.

Wiring and service of the RPM41F7

Use a socket rated for the current and wire with proper cables. Keep the relay away from heat sources.

Replace at the end of the contact life.

Typical applications of the RPM41F7 in Oman and the GCC

In Oman and the GCC power relays are used in heater, lighting and motor-starting control circuits.

Dimensions, environment and approvals of the RPM41F7

The RPM41F7 weighs 0.071 kg. Mounting, derating and enclosure choices follow the environmental data below, which should be compared with the actual panel temperature and the dust and humidity of the site in Oman and the GCC.

Ambient temperature limits in the datasheet: -40 to 55 °C. Vibration resistance: 3 gn ± 1 mm 10 to 150 Hz5 cycles in operation; 5 gn ± 1 mm 10 to 150 Hz5 cycles not operating. Shock resistance: 15 gnin operation; 30 gnnot operating. Standards listed: UL 508; IEC 61810-1; CSA C22.2 No 14. Certifications listed for this reference: UL; CSA; EAC.

The RPM41F7 is large enough that its operating noise and heat are noticeable, so spacing and cabinet airflow should be reviewed. A 15 A power relay with four poles can switch several circuits at once, but the sum of the contact currents on one coil should stay within the thermal limits stated in the datasheet, not simply four times the single-pole value. A typical use is a master relay that drops several outputs together after an alarm; here the lockable test button helps when you need to check the dropped state without a real alarm. In older plants with a 120 V AC control supply this relay often replaces larger contactors that were oversized for the load. Document the coil voltage on a label near the socket, because 120 V and 230 V versions look the same, and installing the wrong coil voltage destroys the coil within seconds.
