1SDA052315R1 ABB 1/2 Kit 4-Pole E4-A HR to VR Terminal Conversion Kit

Why Choose the ABB 1SDA052315R1 Terminal Conversion Kit?

The ABB 1SDA052315R1 is a genuine ABB terminal conversion kit for Emax E4-A fixed circuit breakers, designed to convert the breaker connection arrangement from horizontal rear terminals to vertical rear terminals. Supplied as a 1/2 kit for a 4-pole breaker, it provides the components required for either the upper or lower terminal set.

As part of the ABB Emax circuit-breaker accessory range, the kit provides a manufacturer-engineered method of adapting the rear connection orientation of an E4-A fixed breaker. This enables greater flexibility when matching the circuit breaker to switchboard busbars, connection geometry and available installation space.

The 1SDA052315R1 is specified as a 1/2 kit, 4-pole, fixed, horizontal rear to vertical rear (HR>VR) for the E4-A frame. Each kit is prepared for either top or bottom application, with two kits required when converting the complete circuit breaker.

Key Advantages

• Converts horizontal rear terminals to vertical rear terminals.
• Designed specifically for ABB Emax E4-A fixed circuit breakers.
• Suitable for 4-pole breaker configurations.
• Supplied as a 1/2 terminal conversion kit.
• Allows terminal orientation to be adapted to different switchboard busbar arrangements.
• Genuine ABB accessory designed for correct mechanical and electrical integration.

Key Features

• ABB Emax circuit-breaker accessory.
• Rear terminal conversion kit.
• Horizontal rear (HR) to vertical rear (VR) conversion.
• 4-pole configuration.
• Designed for fixed circuit breakers.
• Suitable for the E4-A frame.
• Supplied as a half kit for top or bottom application.
• Two kits are required for complete upper and lower terminal conversion.

Flexible Rear Terminal Configuration

Circuit-breaker terminal orientation affects how busbars and conductors can be routed within a low-voltage switchboard. Converting from horizontal rear to vertical rear terminals allows a compatible E4-A fixed breaker to accommodate a different busbar approach while retaining the existing circuit-breaker platform.

The ABB 1SDA052315R1 provides the dedicated components for converting one terminal side of a 4-pole E4-A breaker. Because each kit is prepared for either top or bottom application, two kits are required when both terminal sets of the complete circuit breaker are to be converted.

Typical Applications

• ABB Emax E4-A fixed circuit-breaker installations.
• 4-pole low-voltage air circuit breakers.
• Horizontal-to-vertical rear terminal conversion.
• Low-voltage distribution switchboards.
• Busbar connection layout modifications.
• Switchboard refurbishment and breaker retrofitting.
• Industrial power distribution systems.
