Why Choose the ABB E463/3KB On-Off Switch?
The ABB E463/3KB is a robust 3-pole on-off switch with three normally open (3NO) contacts designed for switching and isolation duties in electrical distribution systems. Rated at 63 A, it provides simultaneous switching of three conductors and is well suited to use as a main switch in distribution boards and other low-voltage installations.
The E463/3KB is rated for 250/400 V AC operation and incorporates three positively opening normally open contacts. ABB specifies a conditional short-circuit current of 10 kA at 400 V AC when used with the prescribed upstream NH 00 gG fuse protection, providing a dependable switching solution for demanding distribution applications.
Designed as part of ABB's modular command and signalling portfolio, the E463/3KB combines a 63 A per-pole rating with connection capacity up to 25 mm². Its DIN rail format allows straightforward integration into distribution assemblies where reliable three-pole manual on-off control is required.

Reliable Three-Pole Main Switching
The ABB E463/3KB uses three normally open switching contacts so that all three poles are operated together when the switch is moved between its ON and OFF positions. This makes it particularly suitable for three-phase distribution arrangements and other applications where several conductors must be switched simultaneously from a single manual control.
With a 63 A current rating, 250/400 V AC voltage capability and conditional short-circuit rating of 10 kA at 400 V AC when installed with the specified upstream fuse protection, the E463/3KB provides a purpose-designed solution for main switching and distribution-board applications. Its terminals accommodate conductors up to 25 mm², supporting practical installation in higher-current circuits.
Typical Applications
- Main switching in electrical distribution boards.
- Three-phase circuit switching.
- Commercial and industrial electrical installations.
- Building power-distribution systems.
- Switchboards and modular panel assemblies.
- Machine and equipment supply switching.
- Manual ON/OFF control of three-pole circuits.
- DIN rail power switching applications requiring a 63 A rating.
