Low-voltage current transformers of 0,5 class are high preciseness gauges that are used in measuring commercial accounting made in accordance witch the IEC/EN 60044 requirements and other standards - SEV, VDE, BS, ANSI, AS. The active part is fully encapsulated by blue temperature resistant polycarbonate housing. The terminals can be sealed and are accessible from two sides. Busbar fastening clamps are integrated. Option: A support which can be snapped into the housing and fixed on a DIN-bar (35mm). Low voltage current transformers are for 0,72/3 kV voltage. Low voltage current transformers can be: Type | Primary current | A [mm] | B [mm] | C [mm] | TSC1 | 25 ÷ 300 A | ø 22 | --- | --- | TSC2 | 80 ÷ 500 A | 25 | 30 | 12 | TSC4 | 200 ÷ 800 A | 30 | 40 | 15 | TSC5 | 250 ÷ 1000 A | 40 | 50 | 20 | TSC6 | 400 ÷ 1200 A | 50 | 60 | 30 | TSC8 | 600 ÷ 2000 A | 60 | 80 | 30 |
For metering purpose | (cl. 0.5) | | Secondary current: | 1 or 5 A | Output: | 2 - 15 VA, depending on the rated primary current |
Low-voltage current transformers for metering and protection: | primary current: | secondary current: | | 50 A .... 200 A | 1 A or 5 A | | 100 A .... 2000 A | 1 A or 5 A | | e.g. 5 + 5 + 5 | 5 A | | as requested | e.g.: 0.1 A |
