Current transformer CTBC17

instrumentencapsulatedPCB

A variant for vertical PCB mounting and a variant for cable connection are available. The cable variant is connected to the evaluators (e.g. CC613, RCMB4xx) via a six-core cable. The RCMB104 and RDC104 evaluators are available for the PCB variant. The measuring current transformers can be used in all earthed and unearthed DC, AC, and 3(N)AC systems. The measuring current transformers feature an integrated magnetic field shielding to prevent interferences from external magnetic fields. The CTBC17 measuring current transformer is particularly characterised by the following features for flexible use in the AC charging infrastructure: Suitable for AC/DC sensitive residual current measurement and monitoring in charging modes 2 and 3 (AC charging) Reliable detection of AC and DC residual currents, thus applicable for residual current detection according to IEC 62752 and IEC 62955 Robust and compact design Internal diameter 17 mm for larger conductor cross-sections Cost-optimised PCB variant for PCB mounting (can be soldered or screwed) Variants with three different cable lengths Features Suitable for AC/DC sensitive residual current measurement acc. to IEC 62752 and IEC 60755 Suitable for DC residual current monitoring to protect RCDs type A in combination with the listed evaluators Shielding to prevent interferences caused by high load currents and external magnetic fields PCB mounting
