ABB MS132-10 MPCB Adjustable Motor Protector

How Does ABB MS132-10 Protect Motors?

The ABB MS132-10 adopts a professional thermal-magnetic tripping mechanism to monitor the operating status of three-phase motors, providing all-round protection against overload, short circuit and phase loss.

① Overload Protection (Thermal Trip) When the motor runs overloaded for a long time with excessive current, the thermal tripping mechanism cuts off the power to prevent motor overheating and burnout.

② Short-circuit Protection (Magnetic Trip) In case of sudden short-circuit faults, the magnetic trip reacts instantly to disconnect high fault current and protect electrical components.

③ Phase Loss Protection The MPCB detects phase failure and phase imbalance, and trips immediately to avoid motor overheating and coil damage caused by abnormal phase loss operation.

FAQ

Q1: How to adjust the current setting of MS132-10? Does it need to match the motor rated current precisely?

A1: There is no need to set a higher value intentionally. Adjust the knob within the 6–10A range according to the rated current shown on the motor nameplate. Equipped with accurate scales for continuous adjustment, it complies with Trip Class 10. It prevents nuisance tripping during motor startup and protects the motor from damage caused by prolonged overload.

Q2: What special working conditions require 100kA high breaking capacity?

A2: It is designed for installations near transformers, grids with electrical noise and workshops with fluctuating loads. Ordinary circuit breakers may get damaged due to insufficient breaking capacity. The MS132-10 withstands 100kA short-circuit current at 400V, ideal for demanding environments such as small water pumps, light machinery and automated production lines.

Q3: Can MS132-10 be used for single-phase motors?

A3: Yes. This 3-pole MPCB works for 400V three-phase 4kW motors as well as single-phase motor circuits. It offers great flexibility for small non-standard equipment and control cabinet retrofits.

Q4: How can I place an order or apply for bulk purchase discounts?

A4: Send your required order quantity via email to Irene8866@163.com, or leave us a message on WhatsApp (+86 18950163907). We will reply within 24 hours with formal quotation and stock confirmation.
