What is ABB MS132-32?

The ABB MS132-32 is a high-breaking rotary Motor Protection Circuit Breaker (MPCB) from the MS132 series. It is widely chosen by manufacturers building high-power motor equipment. It features an adjustable current range of 25A–32A, suitable for 400V 3-phase 15kW industrial motors, and also compatible with single-phase motor applications.

Traditionally, many users combine separate MCBs and thermal overload relays. This solution leads to complicated wiring, limited protection accuracy, and poor resistance under short-circuit faults. This unit solves those pain points effectively.

Compared with the popular MS116 series motor protectors, the biggest advantage of the MS132 series lies in superior short-circuit breaking capacity, up to 100kA. It works excellently in industrial sites with harsh operating conditions, heavy load currents and frequently started & stopped motors.

FAQ

Q1: Can the ABB MS132-32 directly control a 15kW three-phase motor?

A1: It is suitable for 15kW 3-phase motors under 400V working conditions, with an adjustable current range of 25–32A. For selection, prioritize fine-tuning according to the rated current on the motor nameplate instead of relying solely on power rating. This MPCB comes with built-in start-stop control function, so no additional switch is required.

Q2: What is the biggest difference between MS132-32 and the MS116 series?

A2: Both share the same 45mm width. The core difference lies in short-circuit breaking capacity. The MS132 series features superior breaking performance, suitable for sites with complex power grids, frequently started motors and higher short-circuit risks. The MS116 series is applied to standard loads with stable operating conditions.

Q3: Is it necessary to install an extra thermal relay when using the ABB MS132-32?

A3: No. The MS132-32 has built-in overload and phase loss protection with integrated thermal-magnetic trip structure. A single unit provides complete motor protection, eliminating the need for thermal relays and simplifying wiring inside control cabinets.

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.
