IDB-4 Single-Phase and Three-Phase Circutor Differential Type B/AC30mA/DC6mA

The best differential protection to protect your installation against direct current leaks when charging electric vehicles.

Description

Differential protection device for the protection of people and property against fault currents of the following types:
— Continuous residual sinusoidal and pulsating alternating currents.
— Sinusoidal alternating currents of up to 1 kHz.
— Direct currents.
For installations of up to 40 or 63 A and sensitivity of 30 mA.
Instant action.

applications

All electrical installations where process continuity is critical and immediate non-adjustable protections for people (30 mA) are required.
For example:
— Computer systems (SAI)
— Speed ​​variators
— Photovoltaic installations
— Electric vehicle charging systems
