ABB OT160E04CLP 160A 4 pole closed transition manual change-over switch with make-before-break operation, IP65 pistol handle, shaft and bolt set for industrial power transfer applications.
£886.06
The ABB OT160E04CLP is a high quality 160 A closed transition manual change-over switch designed for smooth power transfer between two supply sources in industrial and commercial electrical installations. As part of ABB's trusted OT switch-disconnector range, it uses a make-before-break operating principle to help maintain continuity during switching.
This 4-pole closed transition change-over switch operates without an OFF-position. Between positions I and II, the switch includes an intermediate I+II position where both switches are closed simultaneously for a minimum overlap time of 20 ms. It is supplied complete with a black plastic IP65 I-I+II-II pistol type handle, shaft and bolt set for cable connection.
With a rated operational current of 160 A, robust base-mounted construction and a 90° operating angle, the OT160E04CLP is ideal for switchboards, generator systems, supply transfer panels and low-voltage distribution applications where reliable manual source transfer is required.
Closed transition change-over switches such as the ABB OT160E04CLP are designed to transfer loads between two supply sources using a make-before-break switching sequence. During the transfer, the intermediate I+II position briefly connects both sources, helping reduce interruption time where the electrical system design permits this type of operation.
The OT160E04CLP is well suited to applications where reliable manual switching, clear mechanical operation and robust ABB construction are required. Its 4-pole design allows switching of three phases and neutral, making it a strong choice for industrial panels, supply transfer systems and low-voltage distribution equipment.

The ABB OT160E04CLP is used for manual closed transition switching between two power sources in industrial and commercial electrical systems.
Closed transition means the switch uses a make-before-break operation, briefly connecting both sources in the I+II position before completing the transfer.
This change-over switch has a rated operational current of 160 A.
The OT160E04CLP is a 4-pole switch suitable for switching three phases and neutral.
No. The supplied handle is not padlockable and does not provide door interlocking.
ABB OT closed transition change-over switches are trusted by panel builders, electrical contractors and industrial engineers for reliable manual power transfer in demanding low-voltage installations.
