Air-operated circuit breaker TemPower PRO

three-phaselow-voltageremote-controlled

Overview
TemPower PRO air circuit breakers deliver a compact, user‑oriented protective solution for low‑voltage power distribution. The AX series is offered in Fixed and Draw‑out constructions and in Standard, Smart and High‑fault variants. Smart models provide integrated measurement functions and support optional remote monitoring via a communication module. Measurement accuracy complies with IEC61557-12: ±0.5% (current/voltage) and ±1% (active power). Rear connection terminal direction is configurable; quick connection terminals speed up control wiring.

Key features

• Common outline dimensions for 630AF–1600AF draw‑out frames for compact switchboard integration; significant reductions in weight and volume versus previous models.
• Customer‑configurable rear connection direction (horizontal/vertical) for installation flexibility.
• Quick connection terminals for control circuits to reduce installation time.
• Available Over‑current Release options: Standard type and Smart type (Smart includes measurement and data functions).
• Built‑in measurement functions for circuit information; with optional communication module, remote monitoring and management are supported.
• Improved measurement accuracy: IEC61557-12 compliant (±0.5% current/voltage; ±1% active power).
• TemView PRO remote display compatibility via dedicated cable for panel‑mounted readout of Smart OCR values.
• Fixed type available up to 2000 A rated current.
