$49.61
A 4-pole Type A residual current circuit breaker rated at 40A and 300mA for 400V AC systems, providing reliable protection against electric shocks and leakage currents.
Availability: In stock
Overview
The Siemens 5SV3644-6 is a critical component within the SENTRON protection portfolio, offering reliable and effective residual current operated circuit breaker functionality. Engineered for industrial, commercial, and large residential applications, this device ensures immediate disconnection of the power supply upon detecting earth leakage currents, thereby preventing severe electrical hazards, equipment damage, and electrical fires.
This particular model is a robust 4-pole breaker, suited for three-phase (400V AC) systems. Its Type A classification means it can detect and respond to both sinusoidal AC residual currents and pulsating DC residual currents, covering the majority of common fault scenarios in modern electrical installations.
Key Benefit
-
Enhanced Safety: Protects people and equipment from electric shock and leakage currents.
-
Reliable Performance: Designed by Siemens for consistent and long-lasting operation.
-
Versatile Application: Suitable for residential, commercial, and industrial installations.
-
High Sensitivity: Rated at 300 mA, it quickly detects leakage currents for maximum protection.
-
Easy Integration: 4-pole design allows for efficient installation in multi-phase systems.
Function
-
Detects residual currents (Type A) including pulsating and sinusoidal AC currents.
-
Automatically disconnects power in the event of an earth fault.
-
Operates in 400V AC systems with a nominal current rating of 40A.
-
Provides reliable 4-pole protection for complete circuit coverage.
