About TERASAKI 2500A AIR CIRCUIT BREAKER

Air circuit breaker is a circuit breaker for the purpose of protecting low voltage circuit, mainly for energizing and cutting off high current. It is used as the master of a factory and building, and as a main circuit breaker of a ship, and it is possible to attach various accessories according to the purpose.

Advanced Protection and Reliability

Equipped with an electronic trip unit (Type AT), the TERASAKI 2500A Air Circuit Breaker ensures accurate detection and interruption during overloads and faults. Integrated temperature protection and compliance with IEC 60947-2 provide enhanced reliability and operational safety for your distribution network.

Flexible Installation and Operation Modes

Choose between vertical or horizontal mounting to suit your switchgear layouts. The breaker supports both fixed and withdrawable installations, while its operation can be set to manual or automatic, offering flexibility for maintenance, upgrades, or remote control as required by your facility.

Built for Demanding Environments

Designed with an ambient temperature range of -10C to +50C, the breaker is suitable for challenging industrial settings. Its enclosure provides superior protection-IP30 for chassis installations and IP54 when enclosed-ensuring safety, durability, and minimal maintenance needs.

FAQ's of TERASAKI 2500A AIR CIRCUIT BREAKER:

Q: How does the TERASAKI 2500A Air Circuit Breaker enhance electrical safety in industrial setups?

A: The breaker delivers protection against overload, short circuit, and facilitates isolation through its electronic trip unit. Its high breaking and making capacities (85kA and 187kA peak respectively) ensure safe interruption of fault currents, minimizing potential equipment damage and downtime.

Q: What are the installation options for the TERASAKI 2500A Air Circuit Breaker?

A: You can install the breaker in a fixed or withdrawable configuration, with both vertical and horizontal mounting options available. This flexibility allows for adaptation to various switchgear designs and workspace constraints.

Q: When should auxiliary contacts be specified for this circuit breaker?

A: Auxiliary contacts can be requested when you require remote indication or interlocking with other equipment. These are particularly useful for automation or monitoring systems that need breaker status alerts or control signals.

Q: Where can this air circuit breaker be used with regard to protection levels?

A: With an IP30 protection rate for chassis-mounted and IP54 for enclosed installations, the breaker is suitable for industrial facilities where safety from dust and limited water ingress is required. It adapts well to a range of indoor environments.

Q: What is the electrical and mechanical lifespan of the TERASAKI 2500A Air Circuit Breaker?

A: The breaker has an electrical life of up to 5,000 operations, and a mechanical life of 10,000 operations, ensuring long-term, reliable performance even in frequently operated circuits.

Q: How is temperature protection implemented in this circuit breaker?

A: Temperature protection is integrated through electronic monitoring within the trip unit, quickly responding to thermal overloads to prevent overheating and damage to the system.

Q: What benefits does electronic tripping provide over traditional thermal-magnetic mechanisms?

A: Electronic tripping offers more precise and flexible protection settings, faster fault detection, and better coordination with system requirements. It also allows for custom curves (standard, inverse time, short time, instantaneous) for comprehensive circuit protection.
