Working Mechanism
- On detecting a fault, these 3-pole circuit breakers interrupt the flow of electricity to the circuit and protect the equipment.
- After resolving the fault, the user can reset this circuit breaker by switching the handle to the off & then on position.
- Electronic trip units in these breakers can be used for monitoring & protection of the units.
Features
- The handle, with ON & OFF positions of these Eaton E2LEM type mining electronic moulded case circuit breakers, offer easy identification of the breaker's status.
- These magnetic only or thermal-magnetic circuit breakers have a built-in test port for electronic field testing and a push-to-trip button to check the tripping function during scheduled maintenance.
- They have a current rating of 400 / 600A & a voltage rating of 1000Y (3-phase) / 577VAC & 250VDC.
- These Eaton E2LEM type mining electronic complete moulded case circuit breakers have a trip rating ranging from 1000 to 4000A and 500 to 2500A.
Compatible Accessories
- Shunt Trips: These devices mechanically trip the breakers remotely by applying power (from an external source) to their shunt trip terminals.
- Auxiliary Switches: They connect to these circuit breakers to remotely indicate whether their contacts are open or closed.
- Alarms: They indicate the tripping of the selected breaker during remote operation.
Standards and Approvals
- UL
- IEC
- CSA
Frequently Asked Questions
What are the interrupt ratings of these Eaton E2LEM type mining electronic moulded case circuit breakers?
- 65kAIC at 240VAC
- 35kAIC at 480VAC
- 25kAIC at 600VAC
- 22kAIC at 250VDC
- 10kAIC at 1000Y / 577VAC
What is the difference between a thermal-magnetic type and a magnetic-only circuit breaker?
The thermal-magnetic type breaker has both thermal and magnetic elements for overload trip & inrush / instantaneous trip, respectively. The magnetic-only breakers do not have thermal protection and are mainly used for motor protection.
What are the advantages of a moulded case in these Eaton E2LEM type mining electronic moulded case circuit breakers?
These mining circuit breakers have a moulded case design with an L-frame to house the trip unit & all current-carrying devices inside their frame.
