2 Measuring transformer for universal measuring devices Product description All measuring devices of the PM series can be operated with standard measuring transformers (secondary A or A). To comply with the accuracy class (e.g. 0. S), the measuring device and the measuring transformers used must comply with class 0. S or better. Window-type transformer CTB4/CTB Standards The measuring transformers were designed in accordance with the following standards: IC IC IC 600- Technical data CTB4 Rated continuous thermal I cth.2 x IN Rated short-time thermal Ith 60 x IN, s.2 kv, Ueff 6 kv, U eff, 0 Hz, min 0/60 Hz Operating temperature - 0 C Split-core transformer KBR8/KBR32 Device features CTB4/CTB Window-type transformer Screwless connection technique Maintenance-free, gas-tight connection Max. operating voltages up to.2 kv Can also be used in 690 V systems Unbreakable plastic enclosure, self-extinguishing, UL94-V0, flame-resistant KBR8/KBR32 Split-core transformer (mounting without disconnecting the primary conductor) Incl. connecting cable (2. m) Max. operating voltages up to 0.72 kv Technical data CTB Rated continuous thermal I cth.2 x IN Rated short-time thermal I th 60 x I N, s.2 kv, Ueff 6 kv, U eff, 0 Hz, min 0/60 Hz Operating temperature - 0 C Technical data KBR8 Rated continuous thermal I cth.2 x IN Rated short-time thermal Ith 60 x IN, s 0.72 kv, Ueff 3 kv, Ueff, 0 Hz, min 0 Hz Operating temperature - 0 C Technical data KBR32 Rated continuous thermal I cth.2 x I N Rated short-time thermal I th 60 x I N, s 0.72 kv, U eff 3 kv, U eff, 0 Hz, min 0 Hz Operating temperature - 0 C 2 Measuring--transformer-PQ_D0023_0_D_XXN/06.208

The following table will help you to select the device type. Current transformer secondary PM33(-x) ( A) PMxxx(-xx) ( A) PMxxx-xx ( A) A A ) ) ) Note: In principle, measuring transformers can also be operated with A secondary on measuring devices with A input. In this case, the accuracy class is expected to be reduced by one class (e.g. 0. to ). The measurement accuracy classes of the system The measurement accuracy class of the system is influenced by both the accuracy classes of the measuring transformers und the measuring device.
