Siemens SIRIUS ACT 3SU11 Series Emergency Stop Push Button, 22mm Cutout Diameter, Red - 3SU1150-1HB20-3PH0
This emergency stop push button provides a manual safety shut‑off for industrial control panels, using a mushroom‑style actuator that latches when depressed and is released by a twist action. Designed for front‑panel mounting, it delivers positive opening of contacts for emergency‑off applications and is built to operate across AC and DC control voltages up to 500V. The unit includes a yellow backing plate labelled NOT‑HALT and is suitable for harsh environments with high ingress protection.
Features and Benefits:
• 500V AC 10A thermal current supports high‑voltage circuits
• Two NC auxiliary contacts ensure positive opening safety
• IP66, IP67, IP69 protection allows washdown and outdoor use
• Twist‑release mechanism enables quick manual reset
• Spring‑type terminals permit 2 x 0.25 to 1.5mm² conductor connections
• Two NC auxiliary contacts ensure positive opening safety
• IP66, IP67, IP69 protection allows washdown and outdoor use
• Twist‑release mechanism enables quick manual reset
• Spring‑type terminals permit 2 x 0.25 to 1.5mm² conductor connections
Applications
• Suitable for machine emergency‑off circuits in manufacturing
• Used with control panels requiring panel‑mount safety devices
• Ideal for environments needing washdown‑capable safety switches
• Can be used where positive opening for safety circuits is required
• Used with control panels requiring panel‑mount safety devices
• Ideal for environments needing washdown‑capable safety switches
• Can be used where positive opening for safety circuits is required
What operating voltages does it accept?
It functions on AC and DC systems from 5V up to 500V.
How many switching cycles can be expected mechanically?
Typical mechanical life is around 300,000 operating cycles.
What conductor types are supported at the terminals?
It accepts solid and finely stranded conductors up to 2 x 1.5mm² and AWG24 to 16.
Is the device rated for vibration and shock?
It meets IEC vibration 10 to 500Hz at 5g and shock 15g/11ms sinusoidal half‑wave.
