What does QO breaker mean?
Qwik-Open
These “Qwik-Open” or QO breakers are the fastest opening breakers in use in the industry. They reportedly open after just one full power cycle of a 60 Hz AC line (about 1/60th of a second). These breakers feature a visual trip indicator and make it easy to quickly spot the tripped breaker in the panel.
What is an EPD breaker?
The Square D® Homeline Equipment Protection Device (EPD) Circuit Breakers are 1- or 2-pole thermal-magnetic circuit breakers with integral equipment ground-fault protection. Designed to protect equipment such as heat trace from damage (Class B per UL943), the ground-fault protection level is 30 milliamperes.
What is a LSI breaker?
LSI — A combination of adjustable trip functions including long-time ampere rating, long-time delay, short-time pickup, short-time delay and defeatable instantaneous pickup.
What is a Micrologic trip unit?
Micrologic trip systems use a set of current transformers (called CTs or sensors) to sense the current, a trip unit to evaluate the current m and a tripping solenoid to trip the circuit breaker. Micrologic trip-units are field-interchangeable.
What size breaker is needed for a dishwasher?
When installing a dishwasher, the circuit should be a dedicated 120/125-volt, 15-amp circuit. This 15-amp circuit is fed with a 14/2 NM wire with a ground. You may also elect to feed the dishwasher with a 20-amp circuit using 12/2 NM wire with a ground.
How many mini breakers are in a panel?
The number of breakers can max out to 30-42, too, depending on the design of your 100-amp pane. However, NEC prohibits more than 42 circuits, so you can only choose between 20-42 breakers for a 100-amp panel.
Why choose all MB Breakers?
All MB breakers have only two moving parts – which means better performance and less frequent service intervals. At the lower end of the housing, we added steel reinforcement to not only protect the housing, but to protect the power cell and keep operators running longer.
What is a medium breaker used for on construction sites?
The medium breaker is ideal for concrete and asphalt demolition work, secondary rock breaking and primary rock excavation on construction sites. Weights apply to standard carriers only. Any variances must be agreed with Epiroc and/or the carrer manufacturer prior to attachment.
What is a 15 amp mini-breaker plug fuse used for?
The Cooper Bussmann MB Series 15 Amp Mini-Breaker Plug Fuse has an Edison base and is intended for use as a permanent fuse replacement for most Edison-based fuses. The fuse has a built-in time delay that helps prevent nuisance tripping during appliance start-ups, and the fuse features a button that will restore current when depressed.
Why choose Stanley infrastructure for small mounted breakers?
STANLEY Infrastructure knows what you look for in a small mounted breaker, that’s why our MB series focuses on simplicity, easy maintenance, and powerful breaking performance. All MB breakers have only two moving parts – which means better performance and less frequent service intervals.
