Surge Arrester 4P 12.5kA(10/350) CLASS T1+T2 (B+C) SCHELINGER
Surge Arrester 4P 12.5kA(10/350) CLASS T1+T2 (B+C) SCHELINGER
The SCHELINGER A51-SPD03-4P-B+C is a high-performance surge protective device designed for main distribution boards in residential, commercial, and industrial installations. It combines Type 1 (Class B) and Type 2 (Class C) protection in a single unit, capable of handling direct lightning strikes with a 12.5kA (10/350μs) impulse current per pole. This 4-pole configuration (3L+N+PE) ensures comprehensive protection for three-phase TN-S or TT systems against both direct and induced surges.
With a maximum continuous operating voltage of 275V L-N and 440V N-PE, the arrester safely clamps transient overvoltages while maintaining system integrity. Its robust design includes thermal and overcurrent disconnection for fail-safe operation, and a visual status indicator for easy maintenance. Compliant with IEC 61643-11 and EN 61643-11 standards, this device is ideal for protecting sensitive equipment from lightning and switching surges.
