INSTALLATION RECOMMENDATIONS
INTRODUCTION
EASY REMOVAL
The V-EA* easily snaps onto a readily available, international
standard 35mm DIN Rail. Mounting can be in any position from
full horizontal to full vertical without affecting performance.
Removal, One Pole
1. Insert tip of 4mm or less straight blade screwdriver into the
slot of the metal retaining clip.
All housings are the same size regardless of rated current,
simplifying layout and modifications.
2. Brace the shank of the screwdriver against the terminal
side of the V-EA* and gently lever the clip away from the
DIN rail.
Line power feed can be to either top or bottom terminals. This
provides flexibility to power distribution enclosure entry (top,
bottom, sides) and internal raceway runs (e.g., power in one
horizontal raceway can feed both the row above and the row
below).
3. When the clip moves out, continue rotating screwdriver
and V-EA* up and off of the bottom of the DIN rail lip.
4. Grasp V-EA* and lift upwards to disengage from the top
lip of the rail, then remove.
Minimal free space is required to remove or replace the V-EAs,
and with standard housing and terminal sizes, ratings can be
changed or multi-poles can replace multi-single pole or vice-
versa. To obtain the highest density mounting arrangement
without serious problems from heat build-up, see “Temperature
Correction Curve” (page 22).
Altech and our distributors are pleased to quote custom rail
assemblies. Multi-function assemblies can include cut-to-order
DIN Rail, mounted V-EA and MA circuit breakers, FI Earth
Leakage breakers, lightning/surge protectors, interface modules
(cable fan-out, relays, I/O, power supply, etc.), terminal blocks
with marking tags, and other control components to meet your
specifications. Order assemblies with only one part number or
even your drawing number.
DIN Rail Information
Mounting rails are internationally standardized and are available
in several sizes with or without perforations. Zinc-plated yellow
chromated steel is standard. Copper and aluminum DIN Rails
are also available. Please contact Altech for your DIN Rail
needs.

SNAP-ON MOUNTING
1. Place the upper lip of the V-EA* under the upper lip of the rail.
2. Press down on bottom terminal area until the V-EA* spring-
loaded clip snaps under lower lip of the rail.
