Siemens Mini circuit breaker, 1-pole, 230/400V, 10kA, 32A Part number 5SY4132-7

Product Overview

The 5SY4132-7 is a miniature circuit breaker (MCB) from the SENTRON 5SY4 series. It is a 1-pole, type-C breaker rated for 32 A, suitable for over-load and short-circuit protection in single-phase or multiphase electrical installations. With a breaking capacity of 10 kA, it protects wiring and equipment against faults while fitting standard DIN-rail panels for residential, commercial or light-industrial use.

Key Features

• Single-pole (1P) miniature circuit breaker
• Rated current: 32 A
• Tripping characteristic: Type C — suitable for general loads with moderate inrush currents
• Breaking capacity: 10 kA (at 230/400 V AC) — adequate for typical wiring protection and fault clearing
• Compact design — standard 1-module width, DIN-rail mountable for easy installation
• Protection against overload and short circuit — for circuit and conductor safeguarding
• Compatibility with 230/400 V AC systems — fits a wide range of supply setups

Applications

The 5SY4132-7 is used for over-current protection in residential, commercial, and light-industrial circuits. Typical applications include lighting circuits, socket outlets, small motor feeds, sub-circuits in distribution boards, machinery control panels, and any installation where a compact 32 A single-pole circuit protection device is required. Its Type C characteristic makes it suitable for circuits with some inrush current (e.g. small motors, HVAC fans, lighting circuits).
