Key Features

1
1. High Safety and ReliabilityThe OT800U03 features a dead front construction with terminal shrouds, reducing the risk of touching live parts and improving overall safety and reliability.
2
2. Front Operated MechanismThe switch is designed with a front-operated mechanism, allowing for easy operation and control. The handle and shaft provide door interlock, ensuring the door cannot be opened when the switch is in the on position.
3
3. Modular ConstructionThe modular construction of the OT800U03 makes it easy to integrate into various electrical systems. It can be used equally well with either top or bottom incoming power feed.
4
4. Superior Short Circuit ProtectionThe switch offers superior short circuit protection with a short circuit current rating of 110 kA. This ensures that the switch can handle high current surges without failing.
