The exact value must be verified from the technical data sheet. Trip Unit Type Fixed "AS" Trip Unit • Provides standard non-adjustable or semi-adjustable protection functions (overload and short-circuit). Operation Mechanism Manual stored-energy spring mechanism (allows for quick ON/OFF operation independent of handling speed). Mounting Fixed Mounting (designed for bolted installation in switchgear panels). Standards Compliance IEC/EN 60947-2 Connection Primary power connections are typically made via busbars or large cable lugs bolted to the terminal pads. Standard Accessories The "AS" version typically comes with a basic set of indicators and possibly a few built-in auxiliary contacts. A wide range of additional accessories are available, such as: • Additional Auxiliary Contacts • Undervoltage Release (UV) • Shunt Trip (ST) • Motor Operation Mechanism (for electrical closing) • Mechanical interlocks

The ABB 2TLA010040R0000 — “SENTRY BSR10” — is a compact safety relay / expansion relay designed for industrial safety circuits. It can monitor a simple safety input (e.g. an emergency‑stop button) and provide safety‑rated output contacts, or be used as an expansion relay to increase the number of safe outputs when connected to a main safety relay or safety controller. Supplied by 24 V DC, it supports direct wiring of safety devices in the relay power supply circuit. The relay is DIN‑rail mountable, uses screw‑terminal connections, and is suitable for emergency‑stop circuits, simple machine safety controls, or as output expander in larger safety systems.
