Why Choose the ABB PBC Pushbutton Protection AP/CH E1.2-XT7M?
The ABB PBC Pushbutton Protection AP/CH E1.2-XT7M, order code 1SDA073854R1, is a transparent protective cover for the opening and closing pushbuttons of compatible ABB circuit breakers. Designed for the SACE Emax 2 E1.2 and Tmax XT7M platforms, it helps protect the breaker operating pushbuttons against unintended manual operation.
ABB's PBC system provides a physical barrier over the opening and closing controls while retaining controlled access when operation is required. This version incorporates tool-operated access with an operating slot, making it suitable for switchboards where accidental or casual pushbutton operation needs to be reduced without permanently disabling the breaker controls.
The 1SDA073854R1 is the standard E1.2/XT7M protective-cover version rather than one of ABB's separate padlockable PBC variants. Its transparent construction allows the underlying controls to remain visible, providing a simple mechanical safeguard for industrial, infrastructure and critical-power switchgear.

- ABB order code 1SDA073854R1.
Controlled Access to Breaker Opening and Closing Controls
The opening and closing pushbuttons on an air circuit breaker provide direct manual control of the breaker mechanism. In switchboards where these controls are readily accessible, unintended operation can disrupt electrical distribution or interfere with established operating procedures. The ABB PBC provides a physical protective barrier over both controls to reduce this risk.
The transparent cover maintains visibility of the protected operating area, while the tool-access arrangement allows intentional operation when required. Because the protection is entirely mechanical, it can complement electrical interlocks and control logic without requiring wiring, auxiliary voltage or communication with the breaker trip unit.
Typical Applications
- ABB SACE Emax 2 E1.2 air circuit breakers.
- Compatible ABB Tmax XT7M circuit breakers.
- Industrial low-voltage distribution switchboards.
- Switchgear requiring protection against unintended manual breaker operation.
- Generator and critical-power distribution panels.
- Infrastructure, utility and process-industry electrical systems.
