Siemens 5sv53446 Pure Differential Switch 40A 4P TYPE A 30MA

Technical description:

The Siemens 5SV53446 pure differential switch is a protection device designed to ensure the safety of electrical installations by interrupting the circuit in the event of a current leakage. This model offers effective protection against type A earth fault currents, with a sensitivity of 30mA, and is suitable for residential and industrial applications.

• Rated current: 40A
• Number of poles: 4P
• Type of protection: Type A (protection against sinusoidal alternating currents and unidirectional pulsating currents)
• Sensitivity: 30mA (high sensitivity, for protecting people against earth leakage current)
• Rated operating voltage: 230/400V AC
• Regulations: Complies with CEI EN 61008-1 standards
• Mounting: On DIN rail

This differential switch is suitable for protecting systems and people from electrical faults, with the ability to detect current leakage and quickly disconnect the circuit to avoid accidents.
