⚡ Key Features

Combined thermal and magnetic protection in one device — single MPCB replaces a separate motor-rated MCB plus thermal overload relay, saving DIN rail space and inter-device wiring.
Phase-loss and phase-unbalance detection — trips within seconds of a phase failure, protecting the motor from the severe overheating that single-phasing causes within minutes.
Manual reset only — operator must acknowledge and reset the MPCB after a trip, preventing automatic restart that could damage the motor or driven machinery.
Manufactured to IEC 60947-4-1 and IEC 60947-2 — complies with the applicable Indian BIS and IEC international standards for this product category.
BIS certified, CE, cULus (select models) — meets Indian regulatory requirements for use in government, commercial, and industrial electrical installations.
Genuine authorised Siemens product — sourced directly from the official distribution network with full manufacturer traceability and warranty.
GST invoice provided for India orders — valid for corporate procurement, government project orders, and public tender supply via myelectric.in.
Worldwide export available — UAE, Singapore, UK, USA, Sri Lanka & more. Contact +91 94814 00316 for bulk pricing and international shipping.

❓ Frequently Asked Questions

Q: What is the trip class of the 3RV29175FA00 and what motor starting time does it allow?

A: MPCBs are typically rated Class 10 (trips in ≤10 seconds at 7.2× setting current), suitable for normal motors with DOL starting times up to 10 seconds. Heavy-duty motors (large fans, centrifuges, compressors) with longer starting times may need Class 20 or Class 30 protection — check the starting time against the motor’s speed-torque curve and select accordingly.

Q: Can the 3RV29175FA00 replace a contactor + overload relay combination in a motor circuit?

A: The 3RV29175FA00 provides motor short-circuit protection and overload protection in one device — but it cannot make/break motor current under normal operational switching (that is the contactor’s role). For motor starters requiring on/off switching, the 3RV29175FA00 is used as the upstream protection device with a contactor for switching. Some MPCB series include a direct handle for manual starting of small motors without a separate contactor.

Q: Which Siemens accessories are compatible with the 3RV29175FA00?

A: The Siemens 3RV series supports snap-on accessories including auxiliary contacts (OF), alarm contacts (SD), shunt trip coils (MX), undervoltage releases (MN), and comb busbars. Accessories are series-specific — always verify compatibility using the Siemens product catalogue before ordering. myelectric.in can advise on the correct accessory part numbers for the 3RV29175FA00.

Q: What is the difference between a Motor Protection Circuit Breaker (MPCB) and a standard MCB — and why use the 3RV29175FA00?

A: A standard MCB protects against overload and short-circuit only. A Motor Protection Circuit Breaker (MPCB) adds adjustable thermal overload matched to motor FLC, Class 10/20 trip curves for motor starting inrush, and phase-loss sensitivity — making it the correct device for motor branch circuits where a standard MCB would either nuisance-trip on motor starting or fail to protect adequately against slow overloads. Choose the 3RV29175FA00 when the application specifically requires motor protection circuit breaker (mpcb) characteristics.
