Differential switch 2p class A 25A 30mA APR anti-perturbation 2P ABB F427851

Differential Switch 2P Class A 25A 30mA APR Anti-perturbation 2P ABB F427851 F 200 AP-R

Type A for protection against the effects of sinusoidal and pulsating direct alternating earth fault currents. This product offers the best compromise between safety and continuity of service thanks to its immunity to nuisance tripping, protection from indirect contacts and additional protection from direct contacts with a value of (IΔn=30 mA). Its applications are mainly in residential, commercial and industrial environments.

Reference standards and resistance

• Follows IEC/EN 61008-1 standards; IEC/EN 61008-2-1
• Resistance to nuisance trips (wave 8/20) of 3000 A

Protection System

System pro M compact® circuit breakers protect systems from short circuits and overloads, in alternating current, direct current, for photovoltaic systems or for use on machines or production plants. Offering differential protection solutions at all low voltage installation levels, from low voltage arrival, to power distribution, up to terminal distribution.

• Pure and magnetothermic differential switches
• Differential locks
• Differential relays with separate toroid (both modular and panel front)
