1SDA073848R1 ABB DLP Door Opening Lock FP E1.2

Why Choose the ABB 1SDA073848R1 Emax 2 DLP Door Opening Lock?

The ABB 1SDA073848R1 is a DLP door opening lock accessory designed for ABB SACE Emax 2 E1.2 air circuit breaker installations. Identified by ABB as DLP Blocco apertura portella FP E1.2, it provides a mechanical door interlocking function associated with the fixed part of a compatible Emax 2 E1.2 withdrawable circuit breaker installation.

The DLP accessory is intended to help control access to the switchgear compartment by linking door opening with the position of the circuit breaker. This mechanical interlocking arrangement supports safer and more controlled switchboard operating procedures by restricting compartment door opening when the breaker is in a position where access should be prevented.

Designed specifically for the fixed part (FP) of the Emax 2 E1.2, the ABB 1SDA073848R1 integrates with the circuit breaker installation without requiring an electrical control supply. It is suited to low-voltage switchboards where mechanical access control forms part of the equipment's operating and maintenance procedures.

Mechanical Door Interlocking for Emax 2 Switchgear

Door interlocking accessories are used in switchgear to coordinate access to a circuit breaker compartment with the operating position of the breaker. The DLP mechanism provides a mechanical relationship between the Emax 2 installation and the switchboard door, helping ensure that access follows the intended equipment operating sequence.

The ABB 1SDA073848R1 is designed for the fixed part of an Emax 2 E1.2 withdrawable circuit breaker. By adding mechanical door opening control to the installation, it supports switchboard designs where access to the breaker compartment must be managed as part of defined switching, isolation and maintenance procedures.

Typical Applications

• ABB SACE Emax 2 E1.2 withdrawable air circuit breaker installations.
• Switchgear compartment door interlocking.
• Emax 2 E1.2 fixed-part installations.
• Low-voltage switchboards and distribution panels.
• Controlled equipment access during switching and maintenance procedures.
• Industrial, commercial and infrastructure power distribution systems.
