Why Choose the ABB 1SDA066938R1 KIT R XT1 4pcs?
The ABB 1SDA066938R1 is a genuine adjustable rear terminal kit designed for four-pole ABB SACE Tmax XT1 moulded-case circuit breakers. As part of the ABB SACE Tmax XT accessory range, it converts compatible XT1 circuit breakers for rear connection, providing a practical solution for low-voltage switchboards and distribution assemblies where connections are required behind the breaker.
Rear terminals allow the main power connections to be routed through the rear of the mounting panel rather than connected at the front of the circuit breaker. The adjustable design provides installation flexibility when arranging busbars and conductors, while the frame-specific construction ensures compatibility with the ABB Tmax XT1 platform.
The KIT R XT1 4pcs contains four adjustable rear terminals for a four-pole XT1 circuit breaker. It is suitable for panel builders, switchgear manufacturers and electrical engineers requiring a compact rear-connected arrangement in industrial and commercial low-voltage distribution systems.

Flexible Rear Connections for Tmax XT Circuit Breakers
Rear terminals provide an alternative to conventional front connections by allowing the main electrical conductors or busbars to connect behind the circuit breaker mounting surface. This arrangement can help simplify the front of a switchboard, improve connection routing and support panel designs where rear-accessible power connections are preferred.
The ABB SACE Tmax XT accessory system uses frame-specific components for dependable circuit-breaker installations. The 1SDA066938R1 kit is matched to the XT1 frame and provides four adjustable rear terminals for a compatible four-pole installation.
Typical Applications
- ABB SACE Tmax XT1 circuit-breaker installations.
- Four-pole low-voltage distribution circuits.
- Rear-connected electrical switchboards.
- Industrial power distribution panels.
- Machine and equipment control panels.
- Busbar systems requiring rear circuit-breaker connections.
