Product FAQs
6 answersHow should I use the ITE E22B040's 40A rating when selecting circuit protection?
The 40A rating is the breaker's rated current. Use it when coordinating circuit protection with the calculated load and conductor ampacity.
What circuit configuration is the E22B040 rated for?
The E22B040 is a 2-pole, single-phase breaker rated at 240VAC. Use the voltage, phase and pole count together when selecting protection for the circuit.
How does the 10kAIC interrupting rating guide selection?
The interrupting rating is 10kAIC at 240V, meaning the breaker can interrupt fault current up to that rating at that voltage. The available fault current at the installation point must not exceed this rating.
How does the thermal-magnetic LI trip protect the circuit?
The thermal-magnetic trip combines long-time protection for sustained overloads with instantaneous protection for high-current faults. This allows delayed response to overloads and rapid response to short-circuit conditions.
What does bolt-on mounting mean for installation?
Bolt-on mounting uses a bolted connection to secure the breaker. Plan installation access so the mounting fasteners can be reached and properly secured.
Where do the outgoing load conductors terminate?
The outgoing conductors terminate at the load-side lug connection. Make a secure lug termination to maintain a sound electrical connection between the breaker and the load wiring.
