TGBMA-63 Magnetic-Only Circuit Breaker Overview
Product Overview
· TGBMA-63 magnetic-only circuit breaker (hereinafter referred to as circuit breaker) is mainly suitable for AC 50Hz/60Hz distribution networks with rated current 1A to 63A, rated voltage 230V or 400V. Used in low-voltage terminal distribution for medical IT power distribution systems, motor protection, building fire protection systems, etc., as a short-circuit protection switch. Can also be used with thermal relays or motor starters to achieve overload protection.
Normal Service Conditions
· Ambient air temperature: Upper limit not exceeding +40℃, lower limit not lower than -5℃, 24h average temperature not higher than +35℃.
· Altitude: Installation site altitude not exceeding 2000m.
· Atmospheric conditions: Atmosphere is clean (no explosive hazardous media, and no gases/dust corrosive to metal or damaging to insulation); Relative humidity at +40℃ ≤50%, higher humidity allowed at lower temperatures (e.g., ≤90% at +20℃). Appropriate measures must be taken against condensation caused by temperature changes.
Normal Installation Conditions
· Installation category: Class II, Class III.
· Installation environment pollution degree: Level 3.
· Protection class: IP20.
· Mounted on TH35-7.5(1.0) standard rails.
· Installation site must be free from significant vibration/shock, rain/snow intrusion.
Normal Storage Conditions
· Storage temperature: Upper limit ≤+70℃, lower limit ≥-40℃.
· Storage humidity: At +25℃, relative humidity ≤95%.
· Storage humidity: At +25℃, relative humidity ≤95%.
