Industrial JTEC-DC-489-1-C-10 Circuit Breaker

JTEC-DC-489-1-C-10 is Techna’s DC-rated miniature circuit breaker (MCB) designed to protect a 125 VDC power circuit in industrial panels. This 1-pole device provides a 10 A current rating and uses a Type C thermal-magnetic trip curve, offering moderate delay for short‑circuit and overload protection. It is UL 489 listed for DC applications and carries an interrupting rating of 10 kA at 125 V DC, ensuring rapid interruption during fault conditions. The breaker is designed for standard DIN rail mounting and is polarity sensitive in DC configurations, so correct wiring per Techna's JTEC DC documentation is required. The model designation JTEC-DC-489-1-C-10 denotes a single-pole, 10 A, 125 VDC MCB with a DC-specific trip characteristic, appropriate for protecting DC control lines, automation circuits, robotics, and other industrial equipment power feeds. In related DC configurations, 2-pole variants exist for higher voltages (125 VDC for 1P and 250 VDC for 2P in series), with the same 10 kA interrupting rating, which helps when expanding protection in multi-line DC distributions. Typical installations include branch protection in DC-powered control panels and distributed automation systems where reliable, code-compliant DC overcurrent protection is required.
