TEM5E series moulded case circuit breaker is one of the new circuit breakers developed by
TENGEN with international advanced technology. It is characterized by comprehensive protection, excellent performance and compact size. The circuit breakers are classified into two types according to their rated ultimate short-circuit breaking capacity (Icu): M type (medium breaking type) and H type (high breaking type), which are ideal products for power distribution and motor protection. It is an ideal product for power distribution and motor protection.
• Use category: See technical parameters table
• Protection grade: IP40 (installed in the small chamber in the cabinet with door frame provided)
• Electromagnetic compatibility: Electromagnetic environment A
• Installation angle: The vertical slope does not exceed 5°
Working and Installation Conditions
• Ambient temperature: The low temperature type is suitable for the -40℃ - +70℃ environment where the mean value does not exceed +35℃ within 24 hours. If below -5℃ or higher than 40℃, derating is required.
• Atmosphere conditions: The relative temperature does not exceed 50% at ambient temperature +40°C, and
higher relative humidity can be allowed at lower temperatures; for example, when the mean monthly minimum
temperature is +25°C, the relative humidity is 90%, considering the condensation that occurs on the surface of
the product due to temperature changes.
• Altitude: Suitable for up to 2000 m; if more than 2000 m, the altitude derating is required.
• Installation category: Main circuit: Class III; the installation category of the auxiliary circuit and control circuit
not connected to main circuit is Class II.
• Pollution degree: 3
• Use category: See technical parameters table
• Protection grade: IP40 (installed in the small chamber in the cabinet with door frame provided)
• Electromagnetic compatibility: Electromagnetic environment A
• Installation angle: The vertical slope does not exceed 5°
