Returns must be received within 30 days after authorization approved. Return requests must be made within 30 days of the receipt date. Failure to call before sending return may result in a delay of your refund.Īll returned merchandise must be in the original manufacturer’s packaging including manuals, accessories, cables, etc. In order to return or exchange (under the warranty guidelines described below) all or part of your order, you must contact us at 86. Installation: Four 9/32" (7.2mm) diameter mounting holes.Īll orders from Boat and RV Accessories may be returned within 30 days from date purchase for a full refund less shipping charges, and a 20% restocking fee if the item is not in its original condition.Terminals: three 5/16" studs and one #10 stud.Rating: 12-36V DC 200A max alternator rating negative ground electrical system only.Isolates loads of 2 batteries, allows charging from 1 source.For use with Delcotron-type alternators.Thus the 48162 with a rating of 200A has a per leg rating of 100A per leg. All Cole Hersee battery isolators have a per leg rating equal to half the alternator rating. Battery isolators also have a "per leg" rating which indicates the maximum current it can deliver to either battery. A 4-stud battery isolator can be used with older pattern alternators (in this case the 4th stud will remain unconnected), but a 3-stud battery isolator cannot be used with the Delcotron-type alternator. The newer alternators were first introduced by Delco and are therefore sometimes called "Delcotron-type alternators". The small 4th stud is for connection to a circuit switched by the ignition switch. Most alternators on new vehicles have an integral electronic voltage regulator that requires the use of the 4-stud battery isolator. ![]() The amp rating of each item is the maximum alternator rating. The integral heat sink provides efficient heat dissipation. The electronic components of the 48162 are embedded to give excellent protection from adverse conditions such as contamination and vibration. It should always operate after the circuit breaker.For vehicles with two batteries the Cole Hersee 48162 isolator electrically isolates the batteries to prevent the battery with the higher charge from draining into that with the lower charge.īoth batteries can be charged simultaneously from one source. It should always operate before the isolator device. Sequence of use when they are in the same circuit It requires maintenance check after every 2 to 5 years. It requires maintenance check after every 10 to 15 years. It can be operated both automatically or manually. It is connected on both the sides of an area. It is found in power generation stations and electrical distribution plants. It is found in power distribution and power generation stations as well as homes. Isolators must be closed first and later circuit breaker need to be closedįollowing table mentions difference between Circuit breaker and Isolator. After the maintenance work on circuit breaker is completed,.On either sides of a circuit breaker, it must be opened before opening Due to the above characteristic, when two isolators are connected.It can open the circuit under no load condition only.Purpose and repairs is known as Isolator or Isolating Switch. The device used to disconnect part of system for maintenance.Examples: Air blast circuit breaker, S56 circuit breaker,.The main reason for its popularity is that, it can break the circuit.It is a device which can make or break the circuit under normalĬonditions either manually or through remote control.Hence circuit breaker can be reused multiple times unlike fuse which can be used only once. It can be reset to normal operation after fault is handled or repaired. It basically interrupts current flow when a fault is detected.It is used to protect electrical circuit from damage as a result of.They are used in control circuits, automation circuits, protection circuits and switching circuits.The relay is used in circuits with lower ampere capacity i.e.Operation of other devices in the same or another electric circuit. The relay is controlled device which opens and closes contacts in order to effect.This page compares Relay vs Circuit Breaker vs Isolator and mentions difference between Relay, Circuit Breaker and Isolator. ![]() ![]() Relay vs Circuit Breaker vs Isolator | Difference between Relay, Circuit Breaker and Isolator
