Although the 9926 series uses a magnetic only trip mechanism, CSA
testing indicates a trip characteristic similar to thermal magnetic trip
mechanisms. No de-rating is required at elevated temperatures.

*Wire sizes: gauges specified are the minimum allowable as per CSA
and UL standards.
The 9926 circuit breakers do not have provisions for marking tags.
A possible solution is to cut the adhesive SchS2 tag rail to length
(approximately 20 mm on a single pole unit so the current rating
remains visible or approximately 30 mm on a two pole unit).
The SchS2 accepts DEK, WS and ESG 8/17 marking tags.
The part number for adhesive SchS2 is 1720600000.

*Wire sizes: gauges specified are the minimum allowable as per CSA and UL standards.
The 9926 circuit breakers do not have provisions for marking tags. A possible solution is to cut the adhesive
SchS2 tag rail to length (approximately 20 mm on a single pole unit so the current rating remains visible or
approximately 30 mm on a two pole unit).The SchS2 accepts DEK, WS and ESG 8/17 marking tags.
The part number for adhesive SchS2 is 1720600000.

Mounting Options
If the product is not vertically mounted in the normal DIN-rail
mounting orientation, a rating factor must be applied. Figure 1
shows a diagram of the rating factor to apply. The published
curves for these circuit breaker products are produced with
the circuit breaker in the vertical mounting position. The rating
factor only applies to the must hold and must trip points of the
curve as the other parts (instantaneous trip point) stay largely
unaffected.
It is important to note that in environments that are exposed to
a high degree of vibration, the cables that connect to the circuit
breaker must be securely held in place, as the breaker is not
designed to carry the weight of the cables. A maximum of 35N
can be applied to the terminal area, in a direction perpendicular
to the mounting axis.
