The OT250E04CLP is a four-pole manual change-over switch designed for closed transition operation, allowing for a make-before-break functionality without an OFF position. It features a simultaneous contact closure at the I+II position with a minimum overlap time of 20 ms, ensuring seamless transition between operational states.

With an operating angle of 90°, the switch includes a black plastic handle with IP65 protection, along with a shaft and bolt set for cable connections. Notably, the handle is not padlockable and lacks door interlocking features.

This switch is rated for operational currents up to 250 A across various voltage levels, including 380 to 415 V, 500 V, and 690 V. The rated operational power can reach up to 250 kW under specific conditions, making it suitable for demanding applications. The unit is designed with a front degree of protection rated at IP20 and supports base mounting for installation.

Further technical specifications include a rated insulation voltage of 1000 V, a rated impulse withstand voltage of 12 kV, and a conventional free-air thermal current of 250 A at a temperature of 40°C. The switch is classified under object classification code Q and adheres to relevant international standards, including RoHS compliance as per EU directives.
