1SDA058316R1 ABB Sealable Protection for PR121 Emax E1-E6

Why Choose the ABB 1SDA058316R1 Sealable Protection for PR121 Emax E1-E6?

The ABB 1SDA058316R1 is a genuine sealable protection accessory for the PR121 overcurrent release, designed for compatible ABB SACE Emax E1-E6 air circuit breakers. It provides a practical means of protecting access to the trip-unit settings once the required protection parameters have been established.

Designed specifically for the PR121 electronic protection release, this accessory supports controlled management of circuit breaker protection settings. Its sealable arrangement can help discourage unauthorised or inadvertent adjustment of configured protection parameters during normal switchboard operation.

As part of the ABB New Emax accessory range, the 1SDA058316R1 is intended for compatible Emax E1-E6 installations using a PR121 release. It is particularly useful in industrial and commercial distribution systems where protection settings are commissioned to defined requirements and subsequent access needs to be controlled.

Protecting Electronic Trip-Unit Settings

Electronic trip units allow circuit breaker protection parameters to be configured according to the requirements of an electrical distribution system. Once these settings have been commissioned, controlling subsequent access can be important because unintended changes may alter how the breaker responds to overload or fault conditions.

A sealable protection accessory provides a physical means of controlling access to the relevant protection-release settings. The ABB 1SDA058316R1 is designed for the PR121 release used with compatible SACE Emax E1-E6 circuit breakers, making it suitable for installations where protection settings need to remain under controlled supervision.

Typical Applications
