Schneider Electric R9L20625 Combi SPU 1P+N 25A permanent and transient surge protector, replaces reference 16301 , it is a limiting system against permanent and transient overvoltages integrated in a 2-pole Automatic General Switch. It represents the ideal solution to limit overvoltages in the network, it guarantees: the continuity of the service in the electrical installation and the protection of electrical and electronic equipment -such as household appliances and computers- and the continuity of service, regardless of the type of overvoltage that occurs : either due to the proximity of a lightning rod, atmospheric discharges, maneuvers in the network, cutting of the neutral conductor.
The Schneider Electric 25A permanent and transient overvoltage limiter protects against overvoltages due to atmospheric causes, thus guaranteeing service continuity. The Schneider Electric R9L20625 permanent and transient overvoltages incorporates:
- Limiter that also protects the MSU coil from overvoltages caused by lightning.
- MSU protection coil. Causes the automatic switch to trip in the event of permanent phase/neutral overvoltages (voltage surges over 275V). Prevents resetting of the circuit breaker while the fault persists. Protects the limiter against permanent faults.
- C60N automatic general switch. Protects against overloads and short circuits. Coordinated with the limiter, automatic disconnection (according to EN 61643-11). Rating: from 25A to 50A.
- Connection diagram • Located on the side, it facilitates the connection of the terminals. Earth Bonding Label (PE).
- Combination Comb • Pre-wired association, reduces wiring time and offers the highest level of protection.
