Siemens Q230H00S01 Three-Phase Circuit Breaker

Siemens Q230H00S01 Molded Case Circuit Breaker is a 3‑pole, plug‑in protection device rated for 120/240 VAC with a nominal current of 30 A. It features common‑trip across all three poles and a 120 VAC shunt‑trip coil for remote shutdown, making it suitable for three‑phase equipment where rapid isolation is required from a control panel or safety interface. With a 22 kA interrupting rating at 240 VAC, it provides robust short‑circuit protection for motors, compressors, pumps, and other HVAC or industrial loads in commercial environments. The unit employs thermal‑magnetic trip technology, delivering both thermal overload protection and instantaneous magnetic trip for fast fault clearing, and is designed for use in Siemens load centers and panels that accept Q‑series molded‑case breakers. In terms of operation, the breaker is specified for 30 A at 40°C, ensuring reliable protection within typical electrical installations, and its plug‑in form factor simplifies replacement in compatible Siemens enclosures. The Q230H00S01’s three‑phase design and remote‑trip capability are particularly advantageous in settings where coordinated shutdown of all phases is required for safety, energy management, or process control in HVAC systems, data centers, and other commercial facilities.
