Description
The ABB CE4T-10R-02 (1SFA619550R1051) is a 22 mm (Ø 22.5 mm) mushroom-head Emergency Stop (E-Stop) pushbutton from ABB’s Modular Line (CE / CP range), designed to comply with EN ISO 13850, IEC 60947-5-5, and EN 60204-1 machinery safety standards. It features a twist-to-release (or pull-to-release — verify actuator type per suffix) red mushroom actuator (typically Ø 40 mm) with a direct-opening (positive break) NC contact block for safety circuit interruption.
Related models:
- CE4T-10R-02 (1SFA619550R1051) → E-Stop, twist-release, red mushroom Ø40 mm, with 1 × NC contact block (10 = 1 NC, R = red, 02 = twist-to-release)
- CE3T-10R-01 / CE3T-10R-11 → Similar E-Stop but earlier/alternate generation or different release action (pull-to-release / key-release — check suffix: -01 often = pull-release; -11 = key-release on some CE3T)
The CE series is a modular system: actuator (mushroom button) + contact block(s) (NC/NO stacked) + legend plate + holder ring — all snap together on a 22 mm panel cutout.
Key Features
- Safety Compliance: Meets EN ISO 13850, IEC 60947-5-5 (positive opening operation — NC contacts force-open when button pressed)
- Actuator: Red mushroom head (Ø 40 mm typical), twist or pull to reset (CE4T-10R-02 = twist-to-release)
- Contact Block: Typically supplied with 1 × NC (Form B, positive break) — can stack additional NO/NC blocks beneath (up to 3–4 depending on depth)
- Mounting: 22.5 mm round hole (DIN 43605) — flush or raised bezel
- IP Rating: IP65 front face (with gasket) — suitable for most industrial panels
- Country of Origin: Sweden / Germany (ABB Global)
