Why Choose the ABB 1SDA066939R1 KIT R XT1 6pcs?
The ABB 1SDA066939R1 is a genuine adjustable rear terminal kit designed for three-pole ABB SACE Tmax XT1 moulded-case circuit breakers. As part of the ABB SACE Tmax XT accessory range, it provides rear-facing power connections for compatible XT1 breakers used in low-voltage switchboards and electrical distribution assemblies.
Adjustable rear terminals allow the main electrical connections to be routed behind the circuit breaker rather than terminating at its standard front connection points. This configuration can simplify busbar and conductor routing in panel designs where rear access is preferred, while the adjustable terminal arrangement provides additional flexibility when integrating the breaker into a switchboard.
The KIT R XT1 6pcs contains six adjustable rear terminals for a three-pole XT1 circuit breaker, providing connections for both sides of the breaker. The kit is manufactured specifically for the XT1 frame and is suitable for professional panel building, industrial power distribution and switchgear maintenance applications.

Flexible Rear Connections for Tmax XT Circuit Breakers
Rear terminals provide an alternative to conventional front connections by allowing incoming and outgoing electrical conductors or busbars to connect behind the circuit breaker mounting surface. This arrangement can help optimise switchboard layouts, keep power connections away from the front of the breaker and provide greater flexibility when designing compact distribution assemblies.
The ABB SACE Tmax XT accessory system uses frame-specific connection components for dependable circuit-breaker installations. The 1SDA066939R1 kit is matched to the XT1 frame and provides six adjustable rear terminals for a compatible three-pole arrangement, forming a complete rear connection set for both sides of the breaker.
Typical Applications
- ABB SACE Tmax XT1 circuit-breaker installations.
- Three-pole low-voltage distribution circuits.
- Rear-connected electrical switchboards.
- Industrial power distribution panels.
- Machine and equipment control panels.
- Busbar systems requiring adjustable rear circuit-breaker connections.
