Siemens 5SV3344-6KL Residual Current Circuit Breaker, 4-Pole, Type A, 40A, 30mA, 400V Original Brand New

Overview

The Siemens 5SV3344-6KL is an instantaneous, 4-pole Residual Current Circuit Breaker (RCCB) designed to provide comprehensive fault current protection in electrical installations. As part of the respected Siemens SENTRON line, this device ensures safety against dangerous electric shock caused by direct or indirect contact, as well as fire hazards resulting from insulation faults.

This Type A RCCB is specifically optimized to detect and respond to sinusoidal AC residual currents and pulsating DC residual currents, making it suitable for standard residential and commercial applications. With a robust design and a 10 kA short-circuit current rating (SCCR), the 5SV3344-6KL guarantees exceptional operational safety and longevity.

Benefit

• Superior Personal Protection: The ultra-sensitive 30 mA trip threshold ensures rapid disconnection, effectively protecting users from lethal electric shock.

• Fire Prevention: Detects and interrupts small earth leakage currents that could otherwise lead to cable overheating and electrical fires.

• Broad Application: Type A capability covers a wide range of common loads and fault types, including those generated by electronic equipment with rectifiers.

• Easy Integration: The standard DIN rail mounting and 4-unit width (72mm) allows for simple and quick installation into any standard distribution board.

• Reliability & Durability: Engineered by Siemens, featuring a typical 10,000 switching cycle mechanical service life.

Function

• Monitors residual currents and disconnects circuits when leakage is detected.

• Provides 4-pole protection for multi-phase electrical systems.

• Prevents potential fire hazards due to earth leakage.

• Complies with international safety standards for residential and industrial installations.
