Description
Megger MS2A Primary Injection Test Set — Portable Overcurrent Testing
The Megger MS2A is a lightweight, portable primary injection test instrument for verifying the operation of overcurrent protection. Delivering up to 240 A of test current with a high-accuracy LED timer, it tests thermal overload relays, magnetic and solid-state relays, moulded-case circuit breakers and ground-fault trip devices — making it ideal for commissioning and maintenance of protective devices.
Key Features
- High current output — up to 240 A, with ranges of 0–5 A, 0–25 A, 0–120 A and 0–240 A.
- Primary injection testing — injects current directly to verify overcurrent devices in place.
- Precision timer — 5-digit bright LED timer, 0–99.999 s / 0–999.99 s, at ±0.005% ±1 digit.
- Solid-state control — triac-based initiating circuit with momentary and maintained output modes.
- Wide device coverage — thermal overload relays, magnetic and solid-state motor overloads, MCCBs, ground-fault trip devices and overcurrent relays.
- Portable — 25 × 35 × 28 cm, 15 kg, 120 V or 240 V input.
- Standards compliant — CE, EN 61010-1 and EN 61326-2-1.
Applications
The MS2A is ideal for commissioning and maintenance teams testing the operation of overcurrent protection — moulded-case circuit breakers, thermal and magnetic overload relays and ground-fault devices — by primary current injection in industrial and commercial installations.
