B102 ammeter clamps are designed to measure current in cables and bars without having to open the
circuit to insert them. They also isolate the circuit on which the output measurement from the clamp is
being taken, thus making them safe to use. Inserting a B102 clamp on cables or bars is easy and
reassuringly safe.

• Leakage current differential measurements (from 500 μA) when searching for faults
• Measuring AC currents up to 400 A
• Jaws: gap: 112mm . Capacity with jaws open: 250 mm.
  Clamping capacity: cable with a maximum diameter of 115 mm
• Current direction: arrow , visible on the side of the clamp, indicating the current’s direction.
  The current is deemed to be circulating in the positive direction when it flows from the current’s
  generator to the current’s consumer.
• Sizes: 2.
  – Measurement current: 4 A: output 1 mV/mA.
  – Measurement current: 400 A: output 1 mV/A.
• Output: voltage output, via a 1.5m-long cable moulded into the clamp and terminating in two 90°
