Why Choose the ABB OT160E03CLP Manual Change-over Switch?
The ABB OT160E03CLP is a 160 A 3-pole manual change-over switch designed for closed-transition power transfer applications. Supplied under ABB product ID 1SCA108468R1001 and forming part of the ABB OT Change-over Switches range, it provides I-I+II-II operation without an OFF position for applications requiring make-before-break source transfer.
Unlike conventional open-transition change-over switches, the OT160E03CLP incorporates an intermediate I+II position in which both switch sections are closed simultaneously. The overlapping contact time is a minimum of 20 ms, enabling closed-transition operation between positions I and II. The operating handle has a 90° operating angle and provides clear I-I+II-II position indication.
With a rated operational current of 160 A and a 3-pole configuration, the OT160E03CLP is suitable for demanding low-voltage power distribution and transfer applications. At 400–415 V it provides an AC-23A rating of 160 A / 90 kW, while the switch is supplied with a black plastic IP65 pistol handle, operating shaft and bolt set for cable connection.
Key Advantages
- Purpose-designed 160 A closed-transition manual change-over switch.
- 3-pole configuration for three-phase electrical systems.
- I-I+II-II make-before-break operation with no OFF position.
- Minimum 20 ms overlapping time with both switch contacts closed.
- Supplied with a black plastic IP65 I-I+II-II pistol handle, operating shaft and cable connection bolt set.
- 160 A / 90 kW AC-23A rating at 400–415 V for demanding switching duties.
Key Features
- ABB OT Change-over Switches series.
- 160 A rated operational current.
- 3-pole manual change-over configuration.
- Closed-transition I-I+II-II operation.
- No OFF position between source I and source II.
- 90° handle operating angle.
- 1000 V rated operational voltage.
- 12 kV rated impulse withstand voltage.
Closed-transition Change-over for Continuous Power Transfer
Closed-transition change-over switches use make-before-break operation rather than passing through an OFF position during transfer. The ABB OT160E03CLP moves from position I through an intermediate I+II position to position II, with both switch sections closed simultaneously for a minimum overlap period of 20 ms.
This operating principle is intended for applications where a closed-transition switching arrangement is required. The OT160E03CLP combines this functionality with a 160 A current rating, three-pole construction and front manual operation, providing a purpose-designed solution for compatible power distribution and transfer switching systems.
Typical Applications
- Closed-transition power source change-over systems.
- Industrial electrical distribution switchboards.
- Three-phase transfer switching installations.
- Power distribution and control panels.
- Applications requiring make-before-break manual transfer.
- OEM switchboards and industrial electrical systems.
