What kind of fuses do power control transformers use?
POWR-PRO time-delay fuses such as the FLSR_ID, LLSRK_ ID, IDSR, or JTD_ID series have sufficient time-delay to permit transformers to perform when the fuses are properly selected in accordance with the NEC®. Fusing Control Transformers With one exception, control transformers are protected the same as regular transformers as discussed below.
Where is the ignition lock fuse box located?
– 5 ampere fuse for the ignition lock. The fuse box in the engine bay contains fuses 1 through 36 and several relays listed below. The fuse box is located on the driver side of the engine compartment. Remove the fuse box panel cover to access these fuses.
How many fuses are required for UL protection?
In addition, UL requires the primary of control power transformers used in controllers having short-circuit ratings in excess of 10,000 amperes to be protected by UL Class CC, J, R, or T fuses. For maximum fuse ratings permitted by the NEC, refer to Table 2for sizing of primary fusing and Table 3for sizing of secondary fusing.
Where are the fuses located in a Mercedes Benz?
The fuse box is located on the driver side of the engine compartment. Remove the fuse box panel cover to access these fuses. This is Front SAM control unit, also known as the N10/1 control unit. Auxiliary Fuse Panel in Trunk, Rear SAM Control Unit.
How many fuses are in a digital input module?
Digital input modules will have one fuse per module. Digital output modules will have one fuse per module. 5. Check the I/O module documentation for on board fusing details and make sure any external fuses coordinate with on board module fuses.
Can a single fuse be used in a neutral conductor?
A single fuse in the neutral conductor provides protection for neutral-to-phase faults, but not for phase-to-ground faults. This is one reason why a single fuse in the neutral is not permitted.
Can a single fuse be used on both sides of a line?
A single fuse in the phase conductor provides protection for both kinds of faults. A single fuse in the neutral conductor provides protection for neutral-to-phase faults, but not for phase-to-ground faults.
When to fuse or not to fuse individual I / O modules?
If I/O modules are electronically fused or current limited there should not be a need to use external fuses. 6. Be aware that in food production or facilities that limit glass, glass fuses may not be allowed. Ceramic fuses are generally a better choice in most applications. 7.
