Megger CB-360-DC DC Circuit Breaker Test Set

Megger CB-360-DC DC Circuit Breaker Test Set

The Megger CB-360-DC is a mobile, high-current test set designed specifically for testing DC circuit breakers. It combines a variable high-current DC output, control circuitry, instrumentation and built-in overload and short-circuit protection in one system. Delivering up to 30,000 A, with a calibrated DC ammeter and a precise six-digit digital timer, the CB-360-DC handles the unique demands of DC breaker testing where precision and reliability are critical — in traction, industrial and utility DC systems.

Key features of the Megger CB-360-DC test set

• Up to 30,000 A DC output – variable high-current DC for primary testing of DC circuit breakers.
• Precision timing – six-digit digital timer (to ±0.0025% of reading) for accurate trip-time measurement.
• Calibrated ammeter – 0–50,000 A ranges with ±5% full-scale accuracy.
• Duty-cycle rated – defined on/off times at each current level (e.g. 15 min at 3750 A; short bursts at 30,000 A).
• Full protection – circuit breakers, overload relays, fuses and a temperature-sensitive interlock.
• Two-section mobile design – separate control and output sections for high-current testing on site.

Megger CB-360-DC applications

• High-current testing of DC circuit breakers in traction and industrial DC systems.
• Trip-time and current-threshold verification on high-speed DC breakers.
• Commissioning and maintenance of DC protection equipment.
