Zero Downtime: Essential Power Maintenance & Circuit Protection
Downtime is expensive. Whether it’s a dead sensor battery stopping a security patrol or a blown fuse halting a production line, small power issues cause big problems. DM Corporation’s Power & Circuit Protection category is dedicated to the essential maintenance items that keep your facility powered and your equipment safe.
We supply high-performance industrial batteries and circuit protection devices in the bulk quantities required by maintenance departments. From keeping your UPS backups ready for a storm to ensuring your multimeters and door locks are powered, these are the consumables you cannot afford to run out of.
The last line of defense. Fuses and breakers sacrifice themselves to save your expensive machinery and electronics from catastrophic damage during power surges or shorts.
DM Corporation stocks the most common “consumable” circuit protection devices found in automotive, industrial, and office equipment. Having the right fuse on hand turns a potential multi-day repair into a 5-minute fix.
Glass and Ceramic Tube Fuses
Standard Protection for Instruments & Appliances
The standard protection for instrumentation and appliances.
Glass Tube (AGC): Allows for visual inspection—you can see if the internal wire is broken. commonly used in older automotive circuits and consumer electronics.
Ceramic Tube (ABC/MDA): Designed for higher thermal and arc protection. If a severe short occurs, the ceramic body contains the explosion and prevents fire. Essential for microwave ovens and heavy power supplies.
Key Features & Applications:
Fast-Acting vs. Slow-Blow: We stock both “Fast-Acting” (for sensitive electronics) and “Time-Delay” (for motors that surge upon startup).
Assortment Kits: handy boxes containing the most popular amperages (0.5A to 20A) so you always have the right match.
Standard Sizes: 5x20mm (European/Metric) and 1/4″ x 1-1/4″ (North American) sizes.
Thermal Circuit Breakers
Push-to-Reset Protection for Overloads
When a fuse blows, it’s gone forever. When a Thermal Circuit Breaker trips, you simply push the button to get back to work.
These compact, single-pole breakers are the exact replacements for the overload protection found on power strips, surge protectors, small generators, and air compressors. They use a bimetallic strip that bends when heated by over-current, snapping the circuit open.
Key Features & Applications:
Resettable: No replacement needed—simply cool down and push to reset.
Panel Mount: Fits standard cutouts for easy replacement on equipment control panels.
Overload Protection: Protects motors and transformers from burning out if they stall or get overloaded.
Current Ratings: Available in common ratings like 5A, 10A, and 15A.
