The Siemens 5SL4232-7RCZ24 is a high-reliability 5SL4 series Miniature Circuit Breaker (MCB) designed for precise overload and short-circuit protection in industrial, commercial, and automation control panels. Featuring a 2-pole configuration, 32A rated current, and Type C tripping characteristics, this MCB delivers a strong 10kA breaking capacity at 415V AC, making it ideal for managing inductive load surges and high fault currents.
10kA Short-Circuit Breaking Capacity: Tested and certified for a 10kA breaking capacity at 415V AC, offering dependable protection against heavy electrical faults.
32A Rated Current & 2-Pole Design: Protects dual phases or phase-and-neutral conductors simultaneously in 2-pole AC electrical distribution circuits.
Type C Tripping Characteristic: Operates instantaneously at 5 to 10 times rated current ($5 \times I_n$ to $10 \times I_n$), making it ideal for inductive loads with moderate inrush currents like small motors, pumps, HVAC units, and heavy lighting.
Modular DIN-Rail Mounting: Standard compact footprint for fast, tool-free snap-on mounting on 35mm DIN rails inside distribution boards.
Finger-Safe IP20 Touch Protection: Equipped with shrouded terminals to prevent accidental direct touch, ensuring safety for panel builders and technicians.
High Siemens Quality: Built to strict SIRIUS/SENTRON quality standards for long mechanical service life and reliable operational performance.

Q1: What is the primary difference between the 32A (5SL4232-7RCZ24) and 40A (5SL4240-7RCZ24) models?
A: The main difference is the current carrying capacity. The 5SL4232-7RCZ24 is rated for 32A, making it suitable for circuits with lower continuous current demands than the 40A model.
Q2: What does Type C tripping characteristic mean for this MCB?
A: Type C characteristic means the breaker trips instantaneously at 5 to 10 times its rated current, preventing unwanted nuisance tripping during normal inductive motor or transformer inrush surges.
Q3: Is this MCB suitable for 415V 2-phase applications?
A: Yes, it is a 2-pole circuit breaker rated for up to 415V AC, making it suitable for two-phase or phase-plus-neutral line protection.
Q4: How is the Siemens 5SL4232-7RCZ24 mounted in a panel?
A: It features a standard modular design for quick snap-on mounting on standard 35mm DIN rails.
Siemens 5ST3 Series Auxiliary Switches / Fault Signal Contacts: Snap-on contacts for remote trip status signaling and PLC alarm indication.
Siemens 5ST3 Series Shunt Trips & Undervoltage Releases: Accessories enabling remote electrical tripping during emergency stops.
Siemens 5ST3 Series Busbars: Pin and fork busbar systems for quick, organized power distribution across multiple MCB modules.
