Eaton MTL SD Modular (SDM) surge protectors
MTL SD Modular (SDM): pluggable 7 mm signal surge protectors – replace without disturbing wiring, make-before-break, optional LED and fuse.
- Pluggable module, replace without touching wiring
- 7 mm width for high packing density
- Make-before-break – no signal interruption
- Optional LED diagnostics and fuse/disconnect
Overview
MTL SD Modular (SDM) builds on the proven MTL SD range with a pluggable design: all protection components sit in a removable plug, so modules can be replaced without disconnecting field wiring.
Key advantages
- Pluggable module for fast maintenance and less downtime
- Ultra-slim 7 mm width for high packing density
- Make-before-break design – no loop interruption or false DCS alarms during replacement
- Optional LED diagnostics and fuse/disconnect versions
- Backward compatible with the traditional SD range
- Testable with the MTL MLDT data surge tester
Models
Plugs and bases for 7 V, 16 V, 32 V and 55 V (MDX, MFX, MXL, MXX variants), feed-through plugs and HC high-current bases.
