CT-AC RCM A310N

Divisible Residual Current Transformer Type A

Divisible residual current transformers are particularly suitable for retrofitting, as they can be installed during operation without interrupting the primary conductor. They are available in KBU and CT-AC designs.

• In conjunction with the UMG measuring devices, the residual current to earth of machines or systems (e.g. insulation faults) can be determined
• Compact design
• Detection of very small currents
• Transformation ratio: 700/1
• Round conductor: Ø 110 ... 310 mm
• Busbar in mm: max. 100 x 20 to max. 200 x 20
• Max. wire diameter in mm: 4 x approx. 44 (rm-500 qmm) or 8 x 33 (rm-300 qmm)
• up to 4 x approx. 124 (rm-500 qmm) or 8 x 92 (rm-500 qmm)
• Dimensions: 235 x 219 mm ... 400 x 416 mm (W x H)
• Suitable for the UMG 96RM-E, UMG 96RM-PN, UMG 20CM, UMG 509-PRO and UMG 512-PRO
