2CTB815708R2000 ABB - OVR T2 3N 80-275S

The ABB 2CTB815708R2000 OVR T2 3N 80-275S is a surge protection device (SPD) designed to safeguard electrical installations from transient overvoltages. This device is a Type 2 surge arrester, indicating its suitability for installation in sub-distribution boards to protect sensitive equipment. It features a 3N configuration, meaning it protects three phases and the neutral conductor. The 80-275S designation specifies a maximum continuous operating voltage (Uc) of 275V and includes a remote signaling contact (S) for status monitoring. With a surge protection capacity of 20 kA, it effectively diverts excess current caused by lightning strikes or switching operations. This SPD provides reliable protection against voltage spikes, preventing damage to connected devices and minimizing downtime. Its robust design ensures long-term performance and enhances the overall safety of electrical systems. The ABB OVR T2 3N 80-275S is an essential component for ensuring the resilience of electrical infrastructure against transient overvoltage events, contributing to the reliability and longevity of electrical equipment. It comes as a single piece per packaging unit.
