01 / MODEL RANGE
One enclosure.
Three switching options.
Choose the control signal and load type first, then select the maximum rated load current. All three types share the same enclosure; the model designation and electrical function differ.

02 / PRODUCT VIEWS
Designed for access.
The MGR-1 D4840-F shown here represents the shared enclosure used by all three F-series types.
03 / PARAMETERS
Compare the three types.
Electrical ratings follow the corresponding standard MGR-1 model. The fused range is available in 10 A, 25 A and 40 A maximum rated load-current options.

05 / FUSE & MAINTENANCE
Replace the fuse.
Simplify maintenance.
The accessible fuse holder supports replacement without changing the complete relay when the fuse has operated and the relay remains serviceable. Commonly available fuse formats help simplify sourcing of suitable replacements.
Before replacementDisconnect power, resolve the cause of the fault and check the relay.
Replacement selectionMatch the specified fuse size, current, voltage, breaking capacity and operating characteristic. Use a fuse rated for the AC or DC circuit concerned.
Need a replacement?Send us the relay model and existing fuse markings to confirm a suitable part.
F SERIES / CONNECTION
Three variants.
Three connections.
Select the matching electrical variant. Load terminals are above and control terminals below. Diagrams show terminal functions; confirm the actual markings. The fuse is built in, and its replacement rating must suit the model and AC or DC circuit.
