Product FAQs
7 answersWhen should I choose the 40A Cutler-Hammer CH240PMPCI?
Choose this 40A breaker when the circuit design calls for that current rating. Coordinate the breaker rating with conductor ampacity and load requirements, rather than selecting it by load current alone.
How does the 120/240VAC rating guide circuit selection?
The 120/240VAC rating guides selection for AC circuit voltage. Check the circuit voltage and conductor arrangement together when selecting this 2-pole breaker.
What does the 2-pole, 1-phase arrangement mean for my circuit?
Choose this arrangement for a single-phase circuit requiring protection on two conductors. Pole count describes the circuit arrangement, while the 40A rating guides current selection.
How do I evaluate the 10kAIC interrupting rating?
The interrupting rating is 10kAIC at 120/240VAC. Compare the available fault current at the installation point with this rating; it must not exceed the breaker's interrupting capacity.
How does the thermal-magnetic LI trip protect a circuit?
The long-time thermal function responds to sustained overloads, while the instantaneous magnetic function responds rapidly to high fault current. This combines overload and short-circuit protection in one breaker.
How is the plug-on connection installed?
The breaker uses plug-on mounting and a plug-in terminal connection. Installation involves seating the plug connection securely, so correct engagement is important for the electrical connection.
Does this breaker require a neutral connection?
No neutral connection is required for the breaker itself. Any circuit neutral is handled separately from the breaker's two protected poles.
